PAPER-FEEDING CABINET.

To all 'who/1a t may concern Be it known that I, F RANK IVI. HOBERG, a citizen of the 'United' States, residing at Green Bay, county of Brown, and State of Wisconsin, have invented"ncw and useful Improvements in Paper-Feeding Cabinets,

of which the following is a specification.

My invention relates to improvements in feeding cabinets for Apaper "packages in which a sheet starter is employed for separating the raised free en'd of a sheet from views.`

Referring lto .1,lthe'bcabinetwalls comprise a back wall A, end walls B,'andV a cover wall C, which includes the front and top of the cabinet and is hinged to the end walls B at b. The cover wall is provided with a spring actuated latch D adapted to engagea catch Z projecting from the back wall, the latch being actuated by a push button d. The package E is supported from the end walls B of the cabinet by a bar F. The package of paper is slitted at G, whereby it is partially severed into a series of superposed sheets which may be successi vel,\7 torn ofi' or separated from each other, substantially along the line of the slits, the outer sheet a in each case being permitted to drop through the lower end of the cabinet to a hanging position, where it may be readily grasped and torn olf. `When the pendent sheet c is torn off, the free end of the next succeeding sheet will occupy a position directly above the slit G, from which position it may be readily discharged by a blast of air directed against this end of the sheet. This end of the sheet may thus be blown backwardly in the direction of the opposing wall of the cabinet and permitted to drop by gravity through the open lower end to the hanging position indicated by the initial sheet e in Fig. l. In said Fig. l, I have secured an air compressing chamber H (preferably a cylinder) to the front wall slits.

C, from which chamber air may be discharged 'through a flattened and tapered nozzle I having an outlet I through which the air may be discharged against the outer surface of the paper' package adjacent to the slit G. The nozzle I is formed to deliver air along a line having `a slight upward `inclination, which however is not great enough to carry the air wholly above the adjacent end of the sheet when the package is nearly exhausted. The package may also be provided with a plurality of slits in different portions thereof, the slits Gr extending inwardly from the ends of the package,

'and one or more'other slits g being formed in the middle portion of the package as 1ndicated by dotted lines in Fig. 1, so that the blast of air will pass under theend of the sheet through at least one of such springv actuated piston-J.. A piston rod K is connected to the piston .l and extends downwardly through the lower end of the cylinder, a handle K being provided at the lowerle'nd of the rod. A Vcoiled'spri'ng L'is interposed between the piston and the lower end of the cylinder. To discharge'` the free end of a sheet, the operator grasps the handle K and draws outwardly thereon, compressing spring L. Upon releasing the handle, piston J is driven upwardly with a quick positive movement, forcing a blast of air through the nozzle I and blowing the free sheet from the top of the package.

Referring to Figs. 2 and 3, it will be observed that the back wall A is provided at each end with flanges B and a curved bottom flange a, having an 11p-turned margin c. But in this construction the cover plate C is hinged to the back wall by a hinge pin M. End walls N are connected with the cover plate and a partition wall O is also connected with the cover plate and is formed to lit between the lianges B of the back wall. This partition plate O is also provided with a flange P at its lower end, which substantially fits the inner surface of the flange a on the back wall. The plate 0 serves as a piston to compress air vin the chamber formed between it and the back wall A. A spring Q interposed between the walls O and A is compressed when the wall O moves backwardly toward the wall A and reacts to restore ythe wall O to normal position when pressure is relieved. The wall O is provided with a nozzle R, which is adapted The chamber H is provided with a to direct air from the compression chamber between walls O and A against the paper package E', whichfis suspended from the.

walls N by a supporting bar F. The package E is provided with slits g, g, similar to the slits G, G in Fig. 1, but the package i portion'of the cabinet backwardlyin the direction ,of the wall A. The air between walls O and A rushes outwardly through the nozzle R and blows the free end of the outer sheet from the top of the package E.

This end'of the sheet then falls by 'gravity between the package and the front wall of the cabinet and hangs as indicated at c Yin Fig. 2, where it can be readily grasped and torn loil along the line of weakness formed by the line of slits g, g,

The Operation may then be repeated for the discharge of the neXt succeeding sheet.

2, A paper feeding cabinet provided with v an air compressing chamber, and a nozzle connected with said chamber adapted to deliver air in the direction of the upper portion .of a paper package insaid cabinet.

3. The combination with the walls of a paper feeding cabinet, of an air compressing chamber therein, a movable piston in said chamber, a spring Yfor actuating said pistonv Yin one direction, a nozzle adapted to deliver air from said chamber across the upper portion of said cabinet, and means for actuating said piston from the exterior in oppositionV t0 the tension ef the Spring,
